DUST-GUARD FOR AXLE-BOXES.

SPECIFICATION forming part of Letters Patent No. 610,147, dated August30, 1898. Application liledMay28,1898. SerialNO. 682,082. (No 150,161.)

in the art to which it appertains to make and,

use the same, reference being had to the accompanying drawings, and tothe figures of reference marked thereon, which form a part of thisspecification.

My invention relates to improvements in dust-guards for the axle-boxesof railwaycars, my object being to prevent the entrance of the dust andthe escape or loss of the oil or lubricating material placed in the box.

My further object is to provide an article of this class which shall besimple in construction, economical in cost, reliable, durable, andefficient in use; and to these ends the invention consists of thefeatures hereinafter described and claimed, all of which will be fullyunderstood by reference to the accom panying drawings, in which isillustrated an embodiment thereof.

In the drawings, Figure 1 is a vertical longitudinal section takenthrough a j ournal-box provided with my improved dust-guard. Fig. 2 is aface view of the dust-guard. Fig. 3 is a section taken through the guardon the line w 01:, Fig. 2. Fig. 4 is a section taken on the line y 3Fig. 2. Fig. 5 is a fragmentary detail view illustrating the overlappingextremities of the packing-ring.

Similar reference characters indicating corresponding parts in theseviews, let the numeral 5 designate a caraxle journal box which is of theordinary or standard construction. The journal 6 of the wheel 7 is shownin place within the box. My improved dustguard is located within thechamber 8 of the box and surrounds the portion 6 of the journal passingthrough the said chamber.

The dust-guard consists of a thin'washerlike ring 9, provided with aplurality of springs 10 and a plurality of tongues 12. The springs andtongues, as shown in the drawings, are formed integral with the washerand bent inwardly from its outer edge toward the gages the journal,while one of the other faces is engaged by the inner inclined portion 9of the washer 9, the third face of the packingring being engaged by thetongues 12. Hence the ring 13 is held in-place by the part 9 of thewasher on one side and the tongue 12 on the other side. The packing-ring1-3 is divided, as shown at-13, to compensate for expansion andcontraction and the wear of the parts. The adjacent extremities of thering are cut away, whereby they are adapted to overlap and form atightjoint. (See'Fig.

The outer portion of the washer 9 is pro vided with an offset 9, inwhich a packingring 14 is located and adapted to press against the wall5 of the chamber 8. This ring 14 is held in place from above byhorizontal lips 9, turned outwardly or in the direction opposite fromthe tongues and the springs 10. These lips are also formed integral withthe washer. The springs 10 press against the opposite wall 5 of thechamber 8 and hold the washer 9 and its packing-rings securely in place,thus preventing the entrance of any dust to or the escape of oil fromthe journal-box.

The washer 9, together with its springs, tongues, and lips, should bemade very thin, whereby the Weight of the material therein, as well asthe cost of the device, is reduced to a minimum.

It must be understood that I do not limit the invention to the detailsofconstruction herein shown, as I am aware that many modifications may beemployed without departing from the spirit of the invention.

Having thus described my invention, what I claim is--- 1. In adust-guard for car-axle boxes, the

vided with tongues engaging the packing-ring on one side, while the bodyof the washer engages it on the opposite side, the washer being furtherprovided with springs engaging the axle-box, whereby the device is heldsecurely in place.

2. In a dust-guard for axle-boxes, the combination of a washersurrounding the journal and provided with tongues formed integral withthe body of the washer and bent inwardly from its outer edge toward thejournal, a packing-rin g engaging the journal and located between thebody of the washer and the tongues,another packing-ring larger than thefirst-named ring, the washer being provided with lips engaging thelarger ring which is held between the lips and the body of the washer,the latter being so constructed as to cooperate with the lips andtongues to hold the packing-rings in place.

3. In a dust-guard for axle-boxes, the combination of a washersurroundingthe journal and provided with tongues formed integral withthe body of the washer and bent inwardly from its outer edge toward thejournal, and a packing-rin g engaging the journal and located betweenthe body of the washer and the tongues.

4. In a dust-guard, the combination of a washer provided with tongues,lips, and springs, all formed integral with the body of the washer, andtwo packing-rings held in place by the tongues and lips, the springs being adapted to hold the dust-guard in operative relation with thejournal and the adjacent portion of the journal-box.

5. In a dust-guard, the combination of a washer adapted to surround thejournal of the axle, a packing-ring held in place by the washer, andsprings formed integral with the washer, bent inwardly from its outeredge and engaging the adjacent portion of the journal-box to hold thedust-guard in place.

6. A dust-guard comprising awasher provided with springs, tongues andlips, all formed integral with the body of the Washer, and twopacking-rings of unequal size held in place on the washer by the tonguesand lips respectively, the washer being shaped to co operate with saidelements, the springs beu ing adapted to engage the adjacent portion ofthe journal-box to hold the dust-guard in place.

7. In a dust-guard for axle-boxes, the combination of a packing-ringadapted to surround the journal, said ring being divided, its adjacentextremities being fashioned to overlap forming a tight joint, and awasher having tongues bent inwardly toward the journal to hold thepacking-ring in place, the

latter being located between the body of the
